Abstract

PURPOSE:To prevent a paper jam accident in an in-line system carrier table unit. CONSTITUTION:In a sheet carrier system with a sheet-fed press 1 and a folding machine 6 coupled directly with each other by a carrier table unit 8, speed control is performed by making the belt speed of the carrier table unit 8 slower than the delivery chain speed of a sheet discharge part 2 and compensating the slowing-down part by increasing the carrier speed of the folding machine 6.

The inline method is one in which the printed paper (3) is not piled once but is directly sent to the folding machine (6) through the conveyance table unit (8) to perform the folding work. In addition, the transport table unit (8) is placed on the discharge tray lifter (9) of the discharge section (2) of the sheet-fed printing machine (1) instead of the pile discharge tray in the normal printing. Has been done. The transport table unit (8) has an endless belt (11) which is driven by a motor (10) so that the speed can be freely controlled, and a table (12) which sucks the paper (3) by a compressor.
The printed paper (3) conveyed by the delivery chain (4) is sucked and sequentially sent to the folding machine (6) side. In addition, (13) is a chain gripper (5)

On the endless belt (11). Then, the chain gripper (5) is opened and the paper (3) is placed on the transport table unit (8). At this time, the paper guide (13) is moved to the paper (3) as described above.
The tip of the is guided in the direction of the endless belt (11). However, occasionally, even if the chain gripper (5) is opened, the paper edge does not fall well onto the transport table unit (8), and as a result, a paper jam accident may occur near the paper guide (13). .

In order to prevent such a paper jam accident, the present invention is directed to the endless belt (1) of the transport table unit (8).
The speed of 1) is made relatively slower than the speed of the delivery chain (4). The speed adjustment is achieved by slowing down the speed of the motor (10) of the endless belt (11). By the way, the speed is reduced by about 10%. Further, the speed of the delivery chain (4) is synchronized with the printing speed of the printer main body. The deceleration of the endless belt (11) must be compensated for on the side of the folding machine (6) which is the next step. Because the tact time through the entire system of the sheet-fed printing machine (1) -folding machine (6) is, for example, 8,0 per hour.
This is because the whole system must be harmonized, such as 00 sheets. Therefore, the speed of the belt (7) of the sheet taking-in table of the folder (6) is increased by increasing the speed of its drive motor (not shown) so as to meet the takt time of the entire system.

By reducing the speed of the endless belt (11) of the transport table unit (8) with respect to the speed of the delivery chain (4), the separation of the paper from the chain gripper (5) is improved and a paper jam accident occurs. It never happens. Further, since the sheet conveying speed of the entire system is compensated by the folding machine (6) side, there is no hindrance to the printing-folding work by the in-line system.
